Abstract: The present invention relates to oral care compositions with an improved teeth whitening effect. This effect is achieved by inclusion in the oral care compositions of certain organic peroxy acids as teeth whitening/bleaching agents, particularly peroxyamidophthalamides together with hydrogen peroxide.

Abstract: The present invention relates to oral care compositions with an improved teeth whitening effect. This effect is achieved by inclusion in the oral care compositions of certain organic peroxy compounds as teeth whitening/bleaching agents, particularly peroxyamidophthalamides, sulphoperbenzoic acid, monoperoxyphthalic acid, and (per)acetylatedperboric acid with imine quaternary salts as catalysts for the peroxy compounds.

Abstract: An oral care composition comprises capsules which comprise an encapsulated gent encapsulated by an encapsulating material stable in the presence of anionic surfactants, said encapsulated agent being capable of providing a cosmetic, sensory, protective or therapeutic benefit to the oral cavity, wherein the capsules' weight average particle size ranges from 100 to 2000 .mu.m and wherein the capsules are capable of being gradually crushed during brushing thereby releasing the encapsulated agent gradually during brushing, the foaming capability being maintained throughout brushing.

Abstract: The present invention relates to anti-microbial cosmetic compositions for the care of the human body or parts thereof, comprising derivatives of histatins or fragments thereof. It has been found that the anti-microbial activity of histatins or their fragments can be significantly enhanced by capping them at the C-terminus or at the C- and N-terminus and/or complexing them with anti-microbially-active metal ions. The thus modified histatins and histatin fragments were found to have a significantly increased activity against a range of microbial strains, and were found to be useful as controlled delivery agents for the metal ions. They are suitable for a whole range of anti-microbial applications, such as anti-plaque, and-caries, anti-bad breath oral applications, deodorant applications, personal hygiene applications and so on, for which they are included in any suitable carrier medium. Preferred are the capped derivatives, which have been complexed with Ag, Cu, Zn or Sn.

Abstract: The invention concerns 2-hydroxyalkenoic acids within a general formula ##STR1## where R' is chosen from: a. C.sub.w H.sub.2w,b. C.sub.y H.sub.2y-1, andc. C.sub.y H.sub.2y OZwhere Z is chosen from H, R" and (CH.sub.2).sub.n OR"R" is chosen from C.sub.m H.sub.2m+1 and (CH.sub.2).sub.n OC.sub.m H.sub.2m+1 ;w is an integer of from 1 to 25y is an integer of from 2 to 25m is an integer of from 1 to 4n is an integer of from 1 to 6Many compounds within the formula are novel and are claimed as such.
